Has any one had any luck just honing the jugs and putting new rings in?

And if I do decide for new rings what size?  Engine is a 72 1600 dual port.

Are they badly scored? Are the cylinders still round?????? How much piston clearance do you have? You can measure it with a feeler gauge between the skit and the cylinder wall. If they are still in good shape you can hone them no problem. you'll need rings for 85.5 pistons. There are no oversize rings.

I had a stock 1600 that smoked so bad you couldn't see the back of the buggy as it went down the road. I used a ball hone to hone the cylinders and it still left a few vertical score marks but with the hone job and new rings it ran nice and clean for a couple seasons before the bottom end let loose.
To make a long story short...Yes I did and it worked great.

I have just freshened up my buggy got new made in china pistons and barrels for $100. It runs great.  Dont think a machine shop will fix your old barrels cheaper than that.

where did you by the heads?

The first engine I ever built was done that way. A 1500. I honed out the jugs and reringed the pistons. New bearings, gaskets, a valve job with new exhaust valves, guides, etc. It had a mild Crower cam, and a Holley 300 Bugspray carb. It smoked a bit after the rebuild but after a 500 mile break in the rings seated and it was a good motor. (This was in 1971).

Got the heads from Brothers VW in Ontario, CA.  $109 w/ exchange.
